Abstract
Speckle detection is essential in many areas of quantitative ultrasound. In this work, speckle is characterized with R = SNR and S = skewness of the amplitude of the ultrasound signal data A. Different powers of A can be used to calculate R and S. Prager et al. [2002] proposed a method for finding the optimum power value, which then was further scrutinized [Martin-Fernandez, M and Alberola-Lopez, C, 2005]. We propose using two different powers of A in R and S, and perform a large number of computer simulations to find these optimal values
